' LEASE-ROD.

Specification of Letters Patent.

Application filed March 9, 1916. Serial No. 83,093.

To all whom it may cancer n:

Be it known that I, LoUIs C. GUENTHER, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Lease-Rods, of which the following is a specification.

My invention relates to an improved construction of lease-rod to form a warp-shed divider for weaving looms.

Heretofore, leaserods constructed of enamel-coated metal tubes whose ends are plugged with wooden members, are objectionable, for the reason that the warpthreads cause innumerable fine grooves in the enamel surface, which, together with the shoulder left by the contiguous tube and wooden plug, frequently causes a breakage of one or'more of such threads when nounting the rod within the shed.

The object of my invention is to provide a grooved wooden filler eXtending the full length of the rod, and the latter wholly incased by a thin metallic member, to respectively retain its true shape and aford a minimum lightness to the rod; to maintain enduring wearing surfaces, and to render the rod to be quickly introduced between the Warp-threads without breakage of the same.

In the accompanying sheet of drawings, wherein like reference characters indicate like parts, Figure l is a plan view of my improved lease-rod; Fig. 2, a cross-section of the latter; Fig. 3, a sectional edge View of the rod; Fig. 4, a plan sectional view of one of the end portions of the rod; Fig. 5, a crosssection taken on line w.--m. of Fig. 3; Fig. 6, a plan view of a warp-shed, showing the application of two of my improved lease-rods therein, and, Fig. 7 a section taken on line y.-y. of Fig. 6.

In carrying out my invention my improved 'lease-rod (designated by reference letter A as a whole,) has a filler member -awhich is preferably constructed from bass wood and eXtending the full length of the rod. The wooden member -wis ovalshaped from end to end, and said member is provided with a V-shaped groove formed throughout its length, in one edge thereof, as at -a in Fig. 2. The filler member -ais 'wholly ncased by a thin metallic strip 6- whose opposed ends are inwardly bent to rest upon the faces of the groove -a in the manner shown at --b b in Fig. 2.

The metallic strip -b-, which forms a case for the rod, is secured upon the filler member a by a plunger and suitable dies, and by means of which the top and bottom ends of the rod are made to curve slightly toward the extreme points of the same, as at --b 6 in Fig. 3.

In practice I find that bass wood, to form a filler member for an article of this nature, gives the best results; as it afords a minimum lightness to the article; it has a close grain, and after being kiln-dried does not shrink or swell, and therefore retains its true shape permanently.

After the filler member has been incased in the member -b the end portions of the groove, left by the inturned edges of the latter member are filled with solder, as at -cin Figs. 4: and 5, in order to provide a smpoth rounded finish at these points of the ro The case -bis constructed from leadcoated thin soft steel, of 30 gage, and which coated metal provides a perfectly smooth and durable wearing surface to receive warpthreads.

I manufacture the 'rod, as described, of different weights, for use according to the size and number of warp-threads for weavng. i

In use the rod is mounted in the shed with its rounded edge -b toward the whiproll -d-, in the manner shown in Fig. 7, and each rod is prevented from displacemcnt by means of a cord 8- which is looped around the said roll and has its free portion attached in a perforation mrformed through each end of therod, as shown in Fig. 6.

By my improved Construction it is seen that I provide an article of this character possessing the advantage of having an ideal smooth and durable wearing surface for warp-threads, thereby lessening friction of the latter, and at the same time the rod having no eXposed joints or shoulders between its end points, renders the article to be quickly mounted without injury or breakage of the threads.
